ATTACHIVIENT TO VAPOR-STOVES.

Specification of Letters Patent.

Patented July 9, 1907.

Application filed February 27,1906. Serial No. 303,288.

To all whom it may concern:

Be it known that I, JOHN H. HERRINGTON, a citizen of the United States,residing at Freeport, in the county of Barry and State of Michigan, haveinvented a new and useful Attachment to Vapor-Stoves, of which thefollowing is a specification.

This invention relates to attachments to gas and oil stoves and likestructures, and has for its object to provide a simply constructeddevice whereby the combustion of the fuel is accelerated and the heatingqualities improved without increase of expense, or the same degree ofheat produced at decreased expense.

With these and other objects in view, which will appear as the nature ofthe invention is better understood, the same consists in certain novelfeatures of construction as hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, andin which corresponding parts are denoted by like designating characters,is illustrated a preferred embodiment of the invention capable ofcarrying the same into practical operation, it being understood that theinvention is not necessarily limited thereto, as various changes in theshape, proportions and general assemblage of the parts may be resortedto` Without departing from the principle of the invention or sacrificingany of its advantages.

The burners of gas or gasolene stoves are generally located centrally ofa large aperture and somewhat belaterally around the utensils supportedupon the gratings or fingers usually employed for that purpose arelargely dissipated, and produce no good results. This placed above theburner, as in that event a much greater proportionate amount of the heatis lest, as will be obvious. To concentrate the heat radiating fromburners of this 'character and prevent Waste of the same, and alsoaccelerate the combustion of the fuel without increasing the amount offuel consumed are the principal objects of the present invention, asabove noted, and the means employed for accomplishing the desiredresults are illustrated in the accompanying drawings, in whch:,

Figure l is a perspective view of a portion of a gas stove ofconventional construction with the improved device applied, thegraduated lids or covers being shown detached. Fig. 2 is a transversesection of the parts shown in Fig. 1.

The improved device comprises an annular plate or base 10 having anoutwardly and downwardly inclined rim or side 11 for bearing upon thetop of the stove indicated at l2, and surrounding the burner aperture 13the plate being spaced above the stove top and also above the burner 14,as shown more clearly in Fig. 2. The plate 10 is also provided with aplurality of relatively small air inlet apertures 15 located at thejuncture of the horizontal and inclined portions of the plate. The inneredge of the plate is formed with a shoulder 16 to support an annularutensil supporting member 17, while the latter is thus adapted todetachably support a smaller member 18. By this means the device isadapted for supporting utensils of various sizes. The inclined rim 11thus bears closely upon the stove top at all points, and no air can passbeneath it, but will freely enter through the air apertures 15, but onlyin such quantities as will be freely absorbed by the flames rising fromthe burner.

It will be noted that the flames are retarded somewhat by the lowerinclined face of the plate, and in position to receive the inlowing jetsof air.which engage the flames at just the point where they will mostreadily absorb the oxygen therein, and thus materially accelerate thecombustion and correspondingly increase the heat, and without increasingthe quantity of fuel con'- suined.

The members 17-18 are provided With lifter sockets as at 19-20, and oneof the apertures 15 is enlarged as shown at 2l in Fig. l, to receive alifter implement, to facilitate the handling of the parts of the device.

The device is simple in construction, inexpensive to manufacture, andadapted to all the various sizesand forms of vapor stoves manufactured.Y

Having thus described the invention, what is claimed is:-

As an article of manufacture, an attachment for gas and vapor stovescomprising a narrow flat circular top ring having :1n interior depressedinwardly projecting,r flange and an outer downwardly and outwardlyspreading skirt or flange reaching to a lower plane than the internalflange and adapted to fit closely on the top plate of a stove over aburner, said attachment having air openings formed therethrough only atthe junction of the circular ring and the outer flange one of saidopenings being shaped to fit a lifting device, and a cover plate fittedto the interior opening and supported by the depressed flange.

In testimony that I claim the foregoing as my own, I have hereto aixedmy signature in the presence of two witnesses.
